Bright beam deflection by steering beams with mixed phase dislocations

摘要

We study the ability of beams carrying mixed step-screw phase dislocations to guide and steer probe beams with nonzero transverse velocity. We report the first experimental demonstration of bright signal beam deflection by steering odd beams of finite length carrying such dislocation. The numerical simulations show that the beam deflection can be ruled by the geometry and orientation of the dislocation.
